Redactions
Draw redaction boxes — drag any rectangle over text, images or regions you want permanently hidden. Multiple boxes per page supported.
Find & Redact — type a name, number or phrase and the tool auto-marks every occurrence on the current page with a redaction box.
Permanently applied — redactions are flattened directly onto each page canvas. The downloaded PDF has no hidden layer — content is truly gone.

Frequently Asked Questions
Is the redacted content permanently removed?
Yes. Redaction boxes are painted as solid filled rectangles directly onto each page canvas. The output PDF is a flat export — the underlying content under the box is not preserved anywhere in the file.
Is my PDF uploaded to a server?
Never. PDF.js renders the file entirely in your browser. No data is ever sent to any server at any point.
How does Find & Redact work?
Type a word or phrase and click Find & Mark. The tool uses PDF.js text layer data to locate all matching positions on the current page and automatically places redaction boxes over each occurrence.
Can I redact across multiple pages?
Yes. Navigate between pages using the Previous / Next buttons. Redaction boxes are stored independently per page and all are applied when you click Apply Redactions.
Can I choose the redaction box colour?
Yes. Colors are available including Black, White, Dark Blue, Dark Red, Dark Green and Dark Gray. Black is the standard colour for legal redaction.
Does Undo work after applying redactions?
Undo and Redo work on the drawing stage — before you click Apply. Once you download the redacted PDF, the changes are permanent in that file. Re-upload the original to start over.
